DeviceNet

Explanation of terms

• DeviceNet is a field bus system that is based on the CAN protocol (Controller Area Network). It makes
possible the networking of actuators and sensors (slaves) with a master control unit (master).
• In the DeviceNet, the Type 1066 control head is a slave device according to the Predefined
Master/Slave Connection laid down in the DeviceNet specification. Polled I/O, Bit Strobed I/O and
Change of State 4 (COS) are supported as I/O connection types.
• In DeviceNet, a differentiation is made between cyclic or event-controlled transmitted process messages
of higher priority (I/O Messages) and non-cyclic management messages of lower priority (Explicit Mes-
sages).
• The protocol corresponds to DeviceNet Specification Release 2.0
NOTE A diskette with configuration files (BUE1066.EDS and BUE1066.ICO) is always delivered
with the DeviceNet models. You can also obtain these files over the Internet.
